Abstract: An irrigation control system with a programmable controller having a high speed central processor and a touch screen monitor for independent and simultaneous operation of multiple watering stations and schedules. The touch screen monitor allows for quick entry of changes to irrigation schedules that can be made while the system is in use, thus preventing service interruption. The irrigation control system will accommodate multiple watering stations with precise accuracy and allows for independent start times for each station. Multiple output terminals permit connection to various watering stations as a pre-programmed, removable thumb drive containing the operating system and application software is connected through a USB port to a high speed central processor. The irrigation method describes using the controller for optimum plant growth and health.
